SPRAYING DEVICE.

Application filed September 19, 1921. Serial No. 501,739.

This invention relates to a device for i sprayingor other purposes where it is desired to suddenly shut off orV promptly admit a iiow of liquid or semi-liquid material. it is especially useful on vehicles which carry tanks for a supply of liquid materials iior sprinklingor spraying streets, roadways, ete. In devices of this sort it is -frequently desirable' that the supply of liquid to the i through the device from pipe l.

sprinlrler or spray-pipe be promptly and entirely shut off so as to 'prevent dripping oit the material in passing over cross-streets, sidewalks, etc. With the present device this object can be easily accomplished without necessitatingthe installation of complicated devices that are apt to get outv of order and require close attention.

The invention will beunderstood from the description in connection with the ac- `tank (not shown) to the connecting member 2. The connecting'member 21s provided with an inlet opening 3 and with a transverse conically shaped openingfl, into which lthe inlet 3 extends.

A hollow plug 5, having a conically shaped outer surface to tit in the conical opening 4, is provided with a side inlet 6 to register with the inlet 3 when plug 5 is in the position to permit the material to pass n The in terior of the plug 5 is threaded as at 7 and 8 to receive the screw-threaded ends ol" pipes `9 and 10 respectively, thek other ends of which are closed. The pipes 9 and l0 are provided with a series of openings or spray nozzles 11 in rows on the sides thereof. One end ot the plug 5 is provided with an eX- tension 12 to which may be attached a convenieut means, such as the sprocket 18 to turn'the plug 5 in the socket or opening 4. y

The other end of the. plug is provided at 14 with an external screw-thread, onto which is threaded a nut l5; a spring'washer 16 is interposed between the nut l5 and a seat l? on the side of the connecting member 2.

The operation is as follows: When it is desired to admit material `from theplug 5 isturned to the position indicated in Fig. 2, whereupon/the material passes through the inlets 3 and 6 to the pipes 9 and side of the pipes and preventing residual material from dripping.

l. `In a device of the class described, a connecting member provided with an inlet and a conical opening, a hollow plug open at both ends and fitted in said conical opening and constitutinga valve Jfor said inlet` a horizontal discharge pipe carried by said plug, said pipe being provided with lateral openings there-in. l Y

2. In a device of the class described, a connecting member provided with an inlet and a conical opening, a hollow plug open at both ends and iittedin said conical opening and constituting a valve for said inlet,v

a horizontal discharge pipe carriedby said plug, said pipe being provided with lateral openings therein in which are inserted spraying nozzles. Y y

3. In a device of they class described, a connecting member provided with an inlet' and a transverse opening, a revoluble hollow member in said opening, said member being open atboth ends thereof and constituting a valve for said inlet, nozzles, passages from said inlet through said revoluble member to said nozzles, the dischargeends of said nozzles being at a higher point than said passage in one position ot' 'said revoluble member. i

4. In a device of the class described, a connecting member provided with an inlet and a conical opening, a hollow plugv fitting in'said opening and constituting a valve for the supply tank to the outlets or nozzles ll, y

me Y

said inle'c-l` and n Spray pipe carried at euch end of said plug. said spray pipes being provided rWilli oiitlelis on one Side thereof'.

5L In a. device of the class described. n connecting member provided. with :in inlet leading kto n transverse opening therein, revolnhle hollow means in Said opening' and kconstituting' a valve for said inlet, discharge nozzles Connected lo smid hollow menne on both sides thereof, said nozzles having their 10 ontletSVv in a plane nbovethe hollow portion of saidi means when Said means is turned to one position.

In testimony whereof affix my signature.
